IMPROVEMENT IN GUlDE-PULLEYS FOR ROPES AND BANDS.

Specification forming part of Letters Patent No. 196,250, dated October 16, 1877 application filed April 3, 1877.

To all whom it may concern:

Be it known that I, GEORGE I-I. REYNoLns, of the city, county, and State of New York, have invented certain new and useful Improvements in Angle-Sheaves for Bands or Ropes used in Transmitting Motion, which improvements are fully set forth in the following specification and accompanying drawing.

This invention, although applicable to supporting and guiding bands or ropes for transmitting motion generally, is more particularly designed for supporting and guiding the ropes used to drive or transmit motion to machinery in mines, and it will here be described more particularly with reference to such use.

The invention consists in various novel constructions of the means used to support and carry the an gle-sheave, round which the driving band or rope is passed, and the sheaves which carry said band or rope to the anglesheave, and conduct it therefrom, whereby the several sheaves may be adjusted to different angles or positions of operation without changing the structine of the column or main support, and numerous other facilities or economies are obtained.

Heretofore it has been customary, in order to transmit motion to machinery in mines, to erect frames having a definite and fixed posi- 7 tion, and of a special structure for support of each angle-sheave and the carrying-sheaves connected therewith, to suit a particular and invariable position of the angle-sheave. This necessitated a different main or supporting frame for each one of a series of such sheaves, according to the different angular sets of the angle-sheaves, and different relative positions of the rope-carrying sheaves pertaining there to, to direct the driving rope or ropes in various lines or directions. By my invention, however, the same main support and same com bination of the angle-sheave and its accompanying rope carrying or guiding sheaves will suflice for all variations in direction of the rope, and the entire structure, including the sheaves, may be readily moved from place to place to suit different requirements or changes pertaining to the transmitting of the motion.

Figure 1 represents a side elevation of a main supporting-column, with its angle and rope-carrying sheaves, and means for carrying and adjusting said sheaves in accordance with my invention; Fig. 2, a vertical section of the same in a plane at right angles to the former figure, and Fi 3 aplan thereof. Fig. 4 is a side view of a clamp on the upper end of the supportingcolumn, viewed in a direction at right angles to that from which the same device is viewed in Fig. 1. g

A is a tubular column, which may have a fixed position given it by setting or shrinking it on a hollow pin or base, Whichmay be bolted to a stone buried in the ground. It is desirable also to brace it by stays or rods attached at their upper ends to cars I) b, and secured at their lower ends to eyebolts passing through bowlders, which are also buried in the ground.

The ears I) I) may be on a clamp, B, which is mounted and secured on the top of the post or column.

O is the sheave-carrier of the structure, and D the pivot or pintle on which the anglesheave E is free to turn. The carrier 0 is of curved or circular form, and is made with a locking-groove, c, in its periphery, to provide carrier 0, to set the sheaves G G nearer to or farther from each other. Furthermore, the sheaves G G are adjustable along with the anglesheave E, as the angular position of the latter is changed, so that said sheaves G G will retain their proper relation with the angleshe.ve F. To this end the carrier O is carried by the pintle or pivot B of the anglesheave E; and not only may said carrier be adjusted around the pivot D, but the pivot D is universally adjustable by means of a ball, f, at the lower end of it, and a socket in the clamp B receiving said ball. This ball-andsocket joint provides for changing the angular position of the sheave E, and correspondingly varying the position of the carrier G and the sheaves G G.

The clamp B is a divided one, being built up in two sections or halves, and is secured to the column A. by a screw-bolt, 9, which passes through both sections of the clamp at some distance below the ballf, and through the column, and so'clampsi and firmly secures I the said clamp on the column Without making it clamp the ball b. Separate screw-bolts h h are inserted through the two sections of the clamp, one on each side of the ball, as close as practicable thereto, for the purpose of tightening the said clamp upon the ball, and so securing the pivot at the desired angle. The very slight elasticity of the sections, though they are of cast-iron, is enough to allow them to free the ball sufficiently to allow it to turn when the bolts h h are unscrewed, and to allow'them to be tightened firmly 011 the ball by screwing up thebolts h h. V

From this description it will be seen that not only the whole apparatus or structure may be readily moved and placed 111 any desired position to adapt it to a variety of circumstances, but the rope guiding and support ing sheaves, and the driving or driven an glesheave, may be set to any required angle, ac-

cording to the direction in. which it is llGSllBt V to lead the rope or ropes,

I claim- 1. The combination of the axial pintle or pivot D, upon which the anglesheave rotates, the supporting post or column A, and the positively-clamping ball-and-socket joint ,7" B, connecting' the said pintle or pivot directly with the said post or column, and, providing forthe adjustment and securing of the said pivot or pintle at various angles relatively to the said post or column, substantiallyas herein described.

7 2. The combination, with'the divided clamp lug-socket B, which forms part of the ball-andsocket joint connection between the pintle or pivot D and the post or'standardA, of the bolt 9, which clamps the two sections of said socket securely to the post or standard withoutclampingthe ball f on the pintle or pivot,

and the bolts h h, which clamp the said sections on the said ball f, substantially as herein described.

3. The carrier G, in combination with the augle-shea e E and the pintle or pivot D,

whereby said sheave-carrier is adjustable in 5. The combination of the anglesheave he carrier (3, the rope guiding and carrying sheaves G G, adjustable around said carrier,

the universally-adjustable pintle or pivot D,

the clamp B, and the post or column A, substantially as specified.
